Most young adults celebrate their 21st birthdays with a couple of friends, a few drinks and a slice or two of birthday cake.
Not Miley Cyrus.
Postponing the festivities until after the American Music Awards (where she was scheduled to perform), the singer responsibly enjoyed a low-key night in on her actual birthday (Nov. 23), posting makeup-free selfies to her Instagram account all the while (her eyebrows are back!).
Of course, the quiet wouldn’t last long for the divisive former Disney star.
The Bangerz singer took to the AMA stage on Sunday to close out the show, wearing cat-printed underwear and partnering with a giant digital kitten for a rendition of "Wrecking Ball."
And Miley wasn’t the only Cyrus generating buzz at the event.
Older half-sister Brandi Cyrus also walked the AMA red carpet, chatting with her sibling pre-show.
"You're my only interview," Miley said to her sister, while Brandi responded, "Homegirl, I am jealous of your jacket, it's fuh-reezing!"
Brandi then blogged about the sisterly run-in, writing: "I got to talk to a lot of amazing people tonight BUT I had the MOST fun chatting with my little sister!"
With business out of the way, Miley was able to celebrate her 21st birthday with a raucous post-awards party, complete with strippers and even little people dressed up as the singer and Robin Thicke.
Joined by One Direction and Kelly Osbourne, Miley was photographed popping champagne and enjoying a cake made in her nude likeness.
